While rabbits are designed to reproduce, there are many reasons why a rabbit might not give birth:
* Being spayed or neutered: This is the most common reason. Spaying or neutering prevents rabbits from being able to reproduce.
* Not being exposed to a male rabbit: Rabbits need to be bred with a male to become pregnant.
* Health issues: Some rabbits may have health issues that prevent them from getting pregnant or carrying a litter to term.
* Age: Older rabbits may not be able to reproduce.
* Individual choice: Some rabbits may simply not be interested in mating.
It's important to remember that rabbits are individuals, and not all rabbits will experience the same life events. Just like humans, some may choose to focus on other aspects of their lives, like companionship and play, rather than reproduction.
